Over time, when stress becomes chronic, it means that all these systems can remain activated for prolonged periods, and that cumulative wear and tear is sometimes referred to as allostatic load.\u201d<\/p>\n<p class=\"TpGGueVENmajZwYgWe\" style=\"display:none\">When everyday demands begin to affect sleep, exercise and eating habits, they impact your ability to recover. <\/p>\n<p class=\"TpGGueVENmajZwYgWe\" style=\"display:none\">\u201cThe effect of stress on sleep is very important, because during sleep it\u2019s not that our brain just switches off, it is an active process of dealing with the information of the day,\u201d Hulst says.<\/p>\n<p class=\"TpGGueVENmajZwYgWe\" style=\"display:none\">During sleep, your brain works to either reinforce or weaken information, so if stress disrupts your sleep, that affects this process and how well you perform the next day.<\/p>\n<p class=\"TpGGueVENmajZwYgWe\" style=\"display:none\">\u201cWe can\u2019t remove all stress from our lives and that shouldn\u2019t be the goal, but I think what matters is whether we have sufficient opportunities to recover,\u201d Hulst says.<\/p>\n<p class=\"TpGGueVENmajZwYgWe\" style=\"display:none\">\u201cPhysical activity, good sleep, social connection and general downtime usually help.\u201d<\/p>\n<p>What can we do to maintain a healthy brain as we get older?<\/p>\n<p class=\"TpGGueVENmajZwYgWe\" style=\"display:none\">Being physically active, avoiding smoking, limiting alcohol, eating a healthy diet and staying socially connected all support a healthy brain.<\/p>\n<p class=\"TpGGueVENmajZwYgWe\" style=\"display:none\">And it\u2019s important to monitor blood pressure, cholesterol, diabetes and hearing loss.<\/p>\n<p class=\"TpGGueVENmajZwYgWe\" style=\"display:none\">\u201cFrom a scientific perspective, some of the most consistent evidence we have is for physical activity,\u201d Hulst says.<\/p>\n<p class=\"TpGGueVENmajZwYgWe\" style=\"display:none\">\u201cOlder adults who are more physically active tend to have better cognitive as well as physical health. And obviously when you\u2019re physically active, usually your cardiovascular system is healthier, and what\u2019s good for your heart is usually good for your brain too.\u201d<\/p>\n<p>Should I be doing Sudoku or crosswords to train my brain?<\/p>\n<p class=\"TpGGueVENmajZwYgWe\" style=\"display:none\">Hulst says you should do Sudoku and other puzzles if you enjoy them, but becoming good at Sudoku in itself isn\u2019t proven to improve brain health.<\/p>\n<p class=\"TpGGueVENmajZwYgWe\" style=\"display:none\">\u201cI would much rather encourage people to think more broadly about how [to] keep your brain active, stay socially connected, curious and engaged with the world,\u201d Hulst says.<\/p>\n<p class=\"TpGGueVENmajZwYgWe\" style=\"display:none\">Trying new activities is just as important for your brain as physical activity in general, she says. For example, if you\u2019re a runner, increasing your running time will benefit your physical health, but won\u2019t have as much effect on your cognitive health.<\/p>\n<p class=\"TpGGueVENmajZwYgWe\" style=\"display:none\">\u201cThere is value in learning something genuinely new, something that asks your brain to acquire a skill or approach information differently. It should be challenging enough that you are learning, but not so difficult that you give up.\u201d<\/p>\n<p class=\"TpGGueVENmajZwYgWe\" style=\"display:none\">Learning new skills challenges your brain to form new connections or use existing connections differently. Over time, that builds cognitive reserve, which helps the brain cope with age-related changes or diseases.<\/p>\n<p class=\"TpGGueVENmajZwYgWe\" style=\"display:none\">That\u2019s why you should be thinking about brain health when you\u2019re young, Hulst says, though you\u2019re never too old to start.<\/p>\n<p class=\"TpGGueVENmajZwYgWe\" style=\"display:none\">\u201cThe habits, experiences, environments that we\u2019re exposed to throughout life all contribute to how resilient the brain is at later stages.\u201d<\/p>\n<p>I\u2019m becoming more forgetful; do I need to be worried? <\/p>\n<p class=\"TpGGueVENmajZwYgWe\" style=\"display:none\">It\u2019s normal to occasionally forget things when we\u2019re tired, busy or stressed.<\/p>\n<p class=\"TpGGueVENmajZwYgWe\" style=\"display:none\">\u201cWhat matters more is a clear and persistent change from how you normally function, particularly if it begins to interfere with everyday life,\u201d Hulst says.<\/p>\n<p class=\"TpGGueVENmajZwYgWe\" style=\"display:none\">\u201cThat\u2019s something worth discussing with a health professional. A sudden marked change in someone\u2019s thinking or memory is different again and should be assessed promptly.\u201d<\/p>\n<p class=\"TpGGueVENmajZwYgWe\" style=\"display:none\">Some of us just aren\u2019t good at remembering some things, like people\u2019s names.<\/p>\n<p class=\"TpGGueVENmajZwYgWe\" style=\"display:none\">\u201cSo if you\u2019re 60 and you forget a name, then it\u2019s nothing new \u2013 it\u2019s just who you are and it\u2019s probably nothing to worry about,\u201d she says.<\/p>\n<p class=\"TpGGueVENmajZwYgWe\" style=\"display:none\">\u201cWhen things really suddenly change, whether your partner or someone close to you is making comments about it, that\u2019s usually when something is off.\u201d<\/p>\n<p class=\"TpGGueVENmajZwYgWe\" style=\"display:none\">Professor Hanneke Hulst is giving a talk titled We don\u2019t have a spare: keeping a healthy brain on August 25 as part of the University of Auckland\u2019s Raising the Bar event.<\/p>\n<p class=\"TpGGueVENmajZwYgWe\" style=\"display:none\">Bethany Reitsma is a lifestyle writer who has been with the NZ Herald since 2019.
